Linux Training :Red Hat Enterprise Linux Systems Administration (System Monitoring Performance Management)

TThe Red Hat Enterprise Linux Systems Administration: System Monitoring and Performance Management course introduces participants to performance management principles, monitoring utilities / tools, and analysis for the RHEL5 Operating Environment. The course includes a review of RHEL5 subsystems, along with the utilities provided to monitor system efficiency including sar and the *stat family of tools. In each area of discussion, emphasis will be placed on writing tools for monitoring and analysis. These tools will include Korn shell scripts, Perl procedures, and C language programs.

This course is the equivalent to Red Hat course 442.

Systems: Red Hat Enterprise Linux Version 5 (all update levels)

Linux Training Prerequisites

It is assumed that the participant has successfully completed the Red Hat Linux Essentials (RH 033) and RHEL5 Systems Administration Essentials (RH 131) courses, or has equivalent system time as a user and a working systems administrator

Linux Training Course duration

This course normally requires three (3) days, approximately 60% lecture, and 40% lab time.

Linux Training Course Objectives

On completion of this course, a systems administrator should be able to:

Describe performance management fundamentals
Use the RHEL5 and third-party tools to analyze performance
Write tools in various languages
Use RHEL5 performance data extensions
View and set kernel-based tuning parameters
Monitor and report on process and thread activity
Modify CPU scheduling and virtual memory operations
Enable dynamic monitoring via SystemTap in all major areas
